SWP 2004 series instruments are AC power display control instruments that use full isolation technology to directly collect voltage and current transformer signals, calculate frequency, voltage, current, and the phase difference between them, and single-phase active power or three-phase active power.
The SWP2004 series includes several AC electricity measurement instruments such as SWP‑HZ, SWP‑AC, SWP‑W, SWP‑COS and SWP‑E. All models use full isolation technology, accept direct voltage and current transformer inputs, and calculate frequency, voltage, current, phase angle, and active power. Display sizes range from 48×48 mm to 160×80 mm and the instruments can be configured for a wide variety of input ranges (0‑600 V, 0‑4 A, etc.).
The devices support analog output (0‑10 mA, 4‑20 mA, 0‑5 V, 1‑5 V) and relay alarm outputs, with optional serial communication (RS‑485, RS‑232C, RS‑422) for networked control. Indicator lights show load nature (COS), fault status (ERR), and power display mode (F/Q). The manual also details wiring diagrams, parameter settings, environmental limits, and safety precautions. This manual is written in Chinese.
